There is no problem if you export only the mesh (Image 1), but if you export it together with Armature, the legs will be broken and the description in Unity will not feel like a toon render. (Image 2)

I haven't found a decent solution so I'll ask you a question. Thank you.

    I found it when I searched overseas sites.
    Scale each object or bone when setting the armature. If the various values ​​such as rotation are negative, it seems that the normal line goes wrong and the bone orientation changes.

    It seems safe to apply and set each value to 1.
